HP MFP Analog Fax Accessory 700 (2EH31A), 33.6 kbps Super G3 Fax Card for LaserJet Enterprise & Managed MFPs

The HP MFP Analog Fax Accessory 700 (2EH31A) is an internal fax card that adds analog fax send and receive to HP LaserJet Enterprise and LaserJet Managed multifunction printers that have a fax accessory slot. It connects the MFP to a standard analog telephone line through an RJ-11 port and faxes at up to 33.6 kbps (V.34), for offices that still exchange documents with public authorities, hospitals, law firms or suppliers by fax.

Once installed, fax settings, address books and send/receive jobs are handled from the MFP control panel and its web interface. Manual and scheduled memory lock let you hold received faxes in memory until an authorised user prints them.

• Installation guide and mounting parts

• The card installs into the MFP's fax accessory slot; after a restart the fax menu appears on the control panel.
• Connect it to an analog line — ideally a dedicated line, not shared with a phone or alarm.
• 33.6 kbps (V.34) sends a typical page in a few seconds when the remote machine also supports V.34; older machines fall back to slower speeds automatically.
• Memory lock keeps received faxes from printing until someone enters a PIN — useful for confidential documents.

• It does not work on ISDN or digital lines, and HP notes it may not work correctly on some digital PBX systems — an analog extension or line is required.
• It will not fit inkjet, consumer LaserJet or non-Enterprise MFPs without the fax accessory slot.
• It is not a fax-to-email or internet fax service on its own.
• It does not include a telephone line — you need an active analog line from your provider.
